2. Hydraulic Jump Theory Hydraulic jumps is a phenomenon that occurs in water moving and encounters energy change (energy loss )due to change in one or …... EXAMPLE 6 : HYDRAULIC JUMP A rectangular horizontal channel 2m. wide, carries a flow of 4 m 3/s. The depth water on the downstream side of the hydraulic jump is 1m.
Calculation Effects & Applications of Hydraulic Jump
I know that a hydraulic jump is formed when a zone of supercritical flow discharges into a zone of subcritical flow, but why exactly is a hydraulic jump formed? From a mechanical point of view, ar... From a mechanical point of view, ar...... a hydraulic jump downstream of the region of impinge- ment (Fig. 1). The slow-moving liquid in the sub-critical region presents degraded heat transfer characteristics, which makes prediction and control of the jump location important in thermal design. This paper examines the difficulties that have been found in using simple jump theory to predict the jump's radial location in jet impinge
Hydraulic Jump Model and Programming in Visual Basic
Hydraulic jumps in conduits containing free surface flow have received practically no attention. This project was conducted to investigate experimentally the main features of such jumps and to obtain limits for conduit choking. how to get guides up on photoshop If y0 < ycr then the flow is supercritical and there is a high probability that a hydraulic jump will occur at some point downstream. This is usually to be avoided. This is usually to be avoided. The calculation of critical depth in a circular pipe is based on the critical flow condition of minimum specific energy which leads to the criterion of equation [8.8].
Why and when does a hydraulic jump occur? Quora
Hydraulic jump occurs when the supercritical flow occurs in a channel of which normal flow condition is subcritical. h2/h1 = ½ (√(1+8F12 )- 1) (4) The Froude number is calculated using this equation: how to calculate annual leave for part time A hydraulic jump is a sudden dissipation of energy caused by a change from super-critical to sub-critical flow. The concept is very similar to sudden expansion in pipe flow, except that hydraulic jumps occur in open-channel flow.

How To Calculate When A Hydraulic Jump Occurs
hydraulic jump looks like when one occurs at a base of a dam, at the water surface when Froude’s number is less than one and one that occurs upstream when Froude’s number is

- A hydraulic jump is a sudden dissipation of energy caused by a change from super-critical to sub-critical flow. The concept is very similar to sudden expansion in pipe flow, except that hydraulic jumps occur in open-channel flow.
- A hydraulic jump occurs in open channel flow whenever supercritical flow (Froude number greater than one) occurs on a slope that isn't steep enough to maintain that supercritical flow. The hydraulic jump provides an abrupt transition to subcritical flow from supercritical flow. A smooth transition from subcritical to supercritical flow is
- Just because supercritical flow is a requirement for hydraulic jumps to occur doesn't mean that it's the fact of supercritical flow that causes the jump. The Froude number simply represents a limiting condition on the flow; if the Froude number is less than 1, jumps won't occur regardless of the geometry of the channel. If you read the WP article carefully, you should start to see that it's
